Kerosene yog ib qho organic compound, uas yog ib feem ntawm cov khoom tau los ntawm cov roj refining. Lo lus "kerosene" los ntawm Greek "keros" txhais tau tias "wax". Lo lus no ("krosene") tau nkag mus rau hauv kev tsim khoom los ntawm cov neeg Askiv thaum lub sijhawm tsim kev loj hlob.
Lub cev muaj zog ntawm kerosene
Lub cev lub cev ntawm cov roj av yog qhov sib dua li dej - thaum sib xyaw nrog nws, nws tsis yaj, tab sis tsim cov yeeb yaj kiab oily ntab saum npoo. Qhov no yog qhov laj thawj tseem ceeb vim li cas nws tsis tuaj yeem tua hluav taws kub hnyiab nrog dej.
Nyob rau xyoo pua 19th, kerosene yog cov khoom siv tshaj plaws rau kev teeb pom kev zoo. Thaum pib, roj av roj teeb yog khoom kim heev uas tsuas yog cov nom tswv muaj peev xwm them taus. Tom qab ntawd, roj av roj tau hloov mus ua ib yam khoom tseem ceeb uas muaj nyob hauv txhua lub tsev.
Hnub no, kerosene yog siv rau ntau yam kev xav tau ntawm tsev neeg ua roj cav, rau cua sov thiab teeb pom kev hauv chav, ua roj rau kev tsim kho tsheb thiabdiesel cav. Feem ntau, qhov ua rau muaj hluav taws kub yog lub teeb tsis muaj roj av lossis kev ua txhaum cai ntawm kev nyab xeeb thaum lub sijhawm ua haujlwm ntawm cov khoom siv hauv tsev uas siv roj av ua roj.
Vim li cas koj tsis tuaj yeem tua hluav taws kub hnyiab nrog dej?
Lo lus nug "vim li cas nws tsis tuaj yeem tua hluav taws kub hnyiab nrog dej" feem ntau nug los ntawm cov neeg uas tsis paub txog lub cev lub cev ntawm cov khoom siv hluav taws xob no. Thaum dej yog tus neeg tua hluav taws ntau tshaj plaws, nws yuav tsum tsis txhob siv los tua hluav taws los ntawm kev kub hnyiab.
Yuav ua li cas thiaj muab tau cov roj hlawv roj?
Kerosene yog cov kua nplaum uas tawg tau. Nws yog tsim nyog sau cia tias dej tsis tua kerosene! Tsis tas li ntawd, cov khoom no yog sib dua li dej - thiab yog tias cov roj hlawv tau nchuav nrog dej, nws yuav ntab mus rau nws qhov chaw tsis tas yuav hlawv. Nyob rau hauv cov ntaub ntawv no, muaj ib tug txaus ntshai ntawm nws kis mus rau txawv cov lus qhia, uas yuav provoke ib tug nce nyob rau hauv qhov hluav taws kub cheeb tsam.
Vim li cas koj tsis tuaj yeem tua hluav taws kub hnyiab nrog dej? Vim tias lub hom phiaj tseem ceeb uas yuav tsum tau ua tiav thaum tshem tawm hluav taws yog txhawm rau txhawm rau nkag mus rau cov pa oxygen mus rau qhov qhib nplaim taws. Thiab qhov no tsis tuaj yeem ua tiav nrog dej.
Koj tuaj yeem tua hluav taws kub hnyiab tau siv cov cuab yeej hauv qab no:
- sand;
- khoom av;
- npuag ntom (koj tuaj yeem moisten nws nrog dej);
- tua hluav taws (nyiam dua).
txhawm rau txhawm rau tua hluav taws zoo, koj yuav tsum tau muab cov nplaim taws los ntawm cov khoom siv saum toj no, siv lub lauj kaub hlau, daim ntawv plywood, duav, rab diav hlau, thiab lwm yam. Nyob rau tib lub sijhawm, cov vapors combustible yuav tsum tso tawm thaum tag nrho cov nplaim hluav taws kub hnyiab tau npog tag nrho nrog cov xuab zeb lossis lub ntiaj teb txaus.
Yog tias hluav taws tshwm sim los ntawm qhov hluav taws kub ntawm cov roj av uas nchuav, koj yuav tsum hu rau lub chaw tua hluav taws tam sim ntawd, txawm tias koj ua rau koj tus kheej. Qhov hluav taws kub tuaj yeem tsis pom nyob hauv qhov khoob hauv qab cov plag tsev thiab tom qab ib ntus flare nrog lub zog ntau dua.
Muaj lwm yam laj thawj vim li cas nws tsis tuaj yeem tua cov roj av nrog dej - cov nplaim hluav taws tuaj yeem kis mus rau cov khoom nyob ib puag ncig, tshwj xeeb tshaj yog tias hluav taws tshwm sim hauv chav nres tsheb lossis chav tsev. Cov khoom smoldering nyob rau hauv ib qho chaw nkag tsis tau rau kev kho yuav ua rau hluav taws rov pib dua.
Yog tias muaj kev pheej hmoo ntawm hluav taws xob hauv cov hluav taws xob uas nyob ze rau ntawm qhov chaw ntawm qhov hluav taws kub, ces cov hluav taws xob yuav tsum tau de-energized sai li sai tau. Yog hais tias cov xov hlau ntes tau hluav taws ua ntej lub sijhawm no, qhov hluav taws kub tuaj yeem tsoo nrog cov xuab zeb qhuav, siv lub duav lossis rab diav rau qhov no.
Txhawm rau kom tsis txhob muaj hluav taws kub, koj yuav tsum ua raws li txhua yam kev ceev faj thaum siv cov khoom siv hluav taws xob los ntawm roj av, tsis suav nrog kev ua haujlwm ze rau qhov qhib hluav taws. Nws yog txwv tsis pub siv cov khoom siv puas lossis puas lawm.
